Concrete using method:
A kind of pipeline robot be by electric pushrod group flexible come execution, by the flexible combination of upper planar delta push rod group, lateral edges push rod group and lower planar delta push rod group, actions such as can climbing, move, shuttle back and forth, below carry out signal explanation with regard to a kind of climbing motion of pipeline robot.
A kind of pipeline robot can realize pipeline climbing motion.Fig. 9 (a) represents in an initial condition, and a kind of pipeline robot is positioned among pipeline, and all electric pushrods are in the shortest state of its length.In the first step, upper planar delta push rod group is extended, lateral edges push rod group is extended, lower planar delta push rod group is constant, overall barycenter rises, and the rubber pad in planar delta bar group is contacted with tube wall, and produces certain impacting force, the maximal friction produced by this clamping force is made to be greater than a kind of gravity of pipeline robot, as shown in Fig. 9 (b).Second step, upper planar delta push rod group length is constant, and lateral edges push rod group length is constant, and lower planar delta push rod group is extended, and the rubber pad in lower planar delta bar group is contacted with tube wall, is fixed on by robot among pipeline, as shown in Fig. 9 (c).3rd step, upper planar delta push rod group is constant, and lateral edges push rod group shortens, and with planar delta push rod group shortening at present, makes the overall barycenter of robot increase, as Fig. 9 (d).4th step, upper planar delta push rod group is constant, lateral edges push rod group is constant, lower planar delta push rod group is extended, rubber pad in lower planar delta bar group is contacted with tube wall, and produce certain impacting force, make the maximal friction produced by this clamping force be greater than a kind of gravity of pipeline robot, as shown in Fig. 9 (e).5th step, upper planar delta push rod group shortens, and lateral edges push rod group is extended simultaneously, and lower planar delta push rod group is constant, makes the overall barycenter of robot increase, as Fig. 9 (f).6th step, upper planar delta push rod group is extended, lateral edges push rod group is constant, lower planar delta push rod group is constant, rubber pad in planar delta bar group is contacted with tube wall, and produce certain impacting force, make the maximal friction produced by this clamping force be greater than a kind of gravity of pipeline robot, as shown in Fig. 9 (g).So far, a kind of pipeline robot completes a complete pipeline climbing motion.
